What this means at home
At 89.2 PPM, mineral scale can build up on fixtures and heating elements, reduce soap lather, and leave visible spotting. Hardness is primarily an aesthetic and appliance concern—not itself a tap-water safety rating.

Frequently asked
Water questions for Moline
Is tap water safe in Moline?+

How hard is the water?+
Nearby USGS observations produce an estimate of 89.2 PPM, or 5.2 grains per gallon, classified as moderately hard. This is not a household tap measurement.
Do I need a water softener?+
There is no high-hardness trigger in this profile. Confirm with a tap test before buying equipment.
